所以我正在处理一个文件上传表单，它似乎丢失了文件超级全局中的信息，从一个步骤到另一个步骤。所以我所做的是在通过验证码验证之前打印出超级全局文件，然后在我通过验证码验证后将其打印出来。在某些方面，我在验证验证码后丢失了信息。我已经尝试将信息存储在cookie和会话变量中，但没有运气。就cookie方向而言，只有当我在验证码验证之前点击刷新时，它才会将文件超级全局信息保存到cookie中。在会话存储方面，它在我验证捕获之前将信息存储在会话变量中，但在我验证了captach之后丢失了它。你们这些人能帮忙吗，并提前感谢。我的代码如下：
$DIRECTORY_NAME = "/home/www/xxx/xxxPhotos/";
$FILES = array();
$SPEAKER_STATUS_DROPDOWN = '<option value="">...</option><option value="Suggested">Suggested</option><option value="Invited">Invited</option><option value="Confirmed">Confirmed</option>';
if (empty($_SESSION['captcha']) || strtolower(trim($_REQUEST['captcha'])) != $_SESSION['captcha']) {
$captcha = false;
} else {
$captcha = true;
}
if (!empty($_POST) && $captcha) {
$UNIQ_ID = $_POST['uniq_id'];
$FORM_ID = $_POST['form_id'];
//$uniqid = createuniqid();
// Upload file
if ($_FILES["file"]["name"] != "") {
if ($_FILES["file"]["error"] > 0)
{
echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
die();
}
else
{
$allowedExtensions = array("jpg","gif","tiff","pdf");
if ($file["file"]['tmp_name'] != '') {
if (!in_array(end(explode(".",
strtolower($file["file"]['name']))),
$allowedExtensions)) {
die($file["file"]['name'].' is an invalid file type!<br/>'.
'<a href="javascript:history.go(-1);">'.
'<< Go Back</a>');
}
}
$filename = "AS_".$uniqid."". strrchr($_FILES["file"]["name"], '.');
move_uploaded_file($_FILES["file"]["tmp_name"],
$DIRECTORY_NAME . $filename);
$filenamequery = ", attachment='$filename' ";
$filenameemailbody = "<br>Attachment: <a href=\"http://www.verney.ca/viewabstract.php?filename=$filename\">http://www.verney.ca/viewabstract.php?filename=$filename</a>";
}
die('reached here');
}

所以上面的代码是我一直在使用的原始代码。它实质上是在验证验证码之后上传文件，这就是我丢失$ _FILES超级全局的地方
答案：感谢所有查看我问题的人。问题是验证码在自己的页面上有一个带有enctype集的表单。因此，$ _FILES超级全局覆盖了表单$ _FILES，当然没有设置。
答案 0 :(得分：0)
您输入的文件名为question_400，因此您需要$_FILES["question_400"]["name"]等。
